"The man’s grandmother told him off and said he should know better and then told him to go home, which he did."

After police arrived they took unconscious Fomin and his bleeding girlfriend to hospital where they are now both recovering.

A police spokesman said: "The three people are all locals and were all drunk.

"It seems the former soldier had previously been in a relationship with the woman and was upset about her having found someone new. Fortunately his grandmother was on hand to stop the situation escalating."

The man is now facing trial for carrying an illegal firearm, attempted murder and assault.
